MKS Instruments Is Trying To Shield Margins With A Multi-Layered Tariff Defense Strategy But Is It Working? 

MKS Instruments delivered a strong performance for the first quarter of 2025, with revenues reaching $936 million and a gross margin of 47.4%, both at the higher end of their guidance. The company’s net earnings per diluted share exceeded expectations at $1.71. The growth in revenue was driven by a recovery in demand in the Semiconductor, Electronics & Packaging, and Specialty Industrial markets, with Semiconductor revenue specifically seeing a 20% year-over-year growth when excluding foreign exchange (FX) influences.
